Polyurethane board has good resistance to many chemicals and can resist the erosion of acids, alkalis, solvents and other chemicals.
[0003] In the production process of polyurethane boards, a cutting device is required for cutting and trimming. The polyurethane board is placed on the upper part of the cutting table, and then the cutting knife is rotated by starting the motor to achieve the cutting operation of the polyurethane board. After the cutting knife is used for a long time, it will be worn and the blade will become stiff. At this time, the cutting knife needs to be replaced to ensure that the cutting knife always remains sharp. The existing replacement method is that the operator uses a tool to loosen the bolts that fix the cutting knife for replacement. This replacement method is too cumbersome, time-consuming and labor-intensive, which reduces the efficiency of polyurethane board cutting. Utility Model Content

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Reference Figure 1 , Figure 5 and Figure 6 The utility model provides an embodiment: a cutting device for processing polyurethane boards, comprising a bracket 1, a mounting bracket 2 is fixedly connected to the outside of the bracket 1, extension plates 23 are fixedly connected to both sides of the lower part of the bracket 1, a conveying assembly 24 is arranged outside the right extension plate 23, a fixing plate 3 is fixedly connected to the top of the mounting bracket 2, cylinders 4 are fixedly connected to both sides of the inside of the fixing plate 3, and the output ends of the two cylinders 4 are fixedly connected to the transverse plates 5, guide rings 6 are fixedly connected to both sides of the outside of the transverse plates 5, and connecting columns 8 are inserted into both sides of the inside of the transverse plates 5. A cutting knife 9 is fixedly connected to the bottom of the two connecting columns 8, mounting tubes 10 are fixedly connected on both sides of the inside of the cross plate 5, a slider 11 is slidably connected inside the mounting tube 10, an insertion rod 12 is fixedly connected to the left side of the outside of the slider 11, a moving rod 13 is fixedly connected to the right side of the outside of the slider 11, a spring 14 is sleeved on the outside of the moving rod 13, a socket 15 is opened inside the connecting column 8, the insertion rod 12 is plugged into the socket 15, guide rods 7 are fixedly connected on both sides of the inside of the mounting frame 2, and two guide rings 6 are slidably connected to the outside of the two guide rods 7.
[0027] When the cutting blade 9 is worn out due to long-term use and needs to be replaced, first, the moving rod 13 is pulled to drive the slider 11 to move horizontally inside the mounting tube 10. The fixed connection between the slider 11 and the moving rod 13 ensures the synchronous movement between them. As the slider 11 moves, the plug rod 12 also starts to move. The plug rod 12 is fixedly connected to the left side of the slider 11, so when the slider 11 moves, the plug rod 12 also moves. In this process, the plug rod 12 squeezes the spring 14 sleeved on the outside of the moving rod 13. Under this squeezing, the spring 14 is deformed and the elastic potential energy is accumulated. When the plug rod 12 is completely out of the socket 15, it means that we can easily take the connecting column 8 and the cutting blade 9 out of the cross plate 5. This design cleverly utilizes the elasticity of the spring 14 and the structure of the plug rod 12, making the replacement of the cutting blade 9 simple and fast. When installing a new cutting blade 9, we only need to insert the connecting column 8 fixedly connected to the upper part of the cutting blade 9 into the cross plate 5. At this time, we no longer need additional operations or tools, just loosen the previously pulled moving rod 13. Under the reaction force of the spring 14, the insertion rod 12 will automatically insert into the inside of the insertion hole 15, thereby completing the installation of the cutting knife 9, making it easy to replace the worn cutting knife 9. When replacing, there is no need to use tools to assist in disassembly. The operation is simple and convenient, saving time and effort, and improving the efficiency of polyurethane board cutting.
[0028] Reference Figure 1 , Figure 2 and Figure 4 A dust removal fan 16 is fixedly connected to the right side of the lower part of the bracket 1, and a collecting box 17 is fixedly connected to the input end of the dust removal fan 16. A filter plate 19 is installed on the right side of the inside of the collecting box 17. A conveying pipe 20 is fixedly connected to the right side of the outside of the collecting box 17. The other end of the conveying pipe 20 passes through the fixed plate 3 and is fixedly connected to the inside of the dust collecting port 21. A drawer 18 is slidably connected to the inside of the collecting box 17. Both sides of the upper part of the dust collecting port 21 are fixedly connected with mounting rods 22, and the tops of the two mounting rods 22 are fixedly connected to the outer sides of the horizontal plate 5.
[0029] During the cutting process of the polyurethane board, when the dust removal fan 16 is started, it will quickly form a strong suction force to suck the waste generated during the cutting process through the dust collection port 21. These waste chips are transported to the inside of the collection box 17 through the conveying pipe 20, thereby realizing the effective collection of waste chips. When the waste chips inside the collection box 17 are full, we only need to easily pull the drawer 18 out of the collection box 17 to clean the waste chips. This design not only simplifies the cleaning process, but also greatly improves the work efficiency. In addition, in order to further improve the effect of waste chip collection, a filter plate 19 is set between the dust removal fan 16 and the collection box 17. This design can effectively filter out larger waste chip particles and prevent them from entering the dust removal fan 16, thereby extending the service life of the dust removal fan 16. At the same time, the setting of the filter plate 19 also improves the collection efficiency of waste chips, ensures the cleanliness of the working environment, and realizes the convenience of collecting waste chips generated when the polyurethane board is cut. The collection of waste chips can keep the workplace clean and reduce workers from slipping or other accidental injuries caused by scattered waste chips. At the same time, collecting waste chips also helps to maintain a clean and safe work area.
[0030] Reference Figure 2 and Figure 3 The conveying component 24 includes a motor 2401, which is fixedly connected to the outside of the right extension plate 23. A screw rod 2402 is fixedly connected to the output end of the motor 2401. Moving blocks 2403 are threadedly connected to the outside of the screw rod 2402 on both sides. Moving plates 2404 are fixedly connected to the tops of the two moving blocks 2403. The two moving blocks 2403 are slidably connected to the inside of the bracket 1. Fixed rods 25 are fixedly connected to the inside of the two extension plates 23 on both sides. The two moving blocks 2403 are slidably connected to the outside of the two fixed rods 25. L-shaped plates 26 are fixedly connected to the upper sides of the moving plate 2404. Electric push rods 27 are fixedly connected to the inside of the two L-shaped plates 26. Positioning plates 28 are fixedly connected to the output ends of the two electric push rods 27.
[0031] When cutting the polyurethane board, first put the polyurethane board in the middle of the two L-shaped boards 26, then start the two electric push rods 27 to move the positioning board 28 fixed at the output end to fix the polyurethane board, and then start the motor 2401, the motor 2401 rotates the screw rod 2402 fixed at the output end, the screw rod 2402 rotates to move the two moving blocks 2403 connected with external threads, the two moving blocks 2403 move to move the moving plate 2404 fixed at the top, the moving plate 2404 moves to move the polyurethane board fixed at the top, and the polyurethane board is moved to the lower part of the cutting knife 9, so that the polyurethane board to be cut can be fixed and the polyurethane board can be automatically transported to the lower part of the cutting knife 9. By fixing the polyurethane board, the stability and precise positioning of the board during the cutting process can be ensured. Automatic transportation can accurately transport the polyurethane board to the lower part of the cutting knife 9, ensuring the accuracy and consistency of the cutting position, thereby obtaining a high-quality cutting result.
[0032] Working principle: When the cutting device is used to cut the polyurethane board, when the cutting knife 9 needs to be replaced, the moving rod 13 is pulled. When the moving rod 13 moves, the slider 11 fixedly connected to the outside moves horizontally inside the mounting tube 10. When the slider 11 moves, the plug rod 12 fixedly connected to the outside on the left side moves. When the slider 11 moves horizontally inside the mounting tube 10 with the plug rod 12, the spring 14 sleeved on the outside of the moving rod 13 is squeezed, so that the spring 14 is deformed under force. Then, when the plug rod 12 is separated from the inside of the socket 15, the connecting column 8 and the cutting knife 9 can be taken out from the inside of the cross plate 5 for replacement. During installation, it is only necessary to insert the connecting column 8 fixedly connected to the upper part of the cutting knife 9 into the inside of the cross plate 5, and then loosen the moving rod 13. Under the reaction force of the spring 14, the plug rod 12 is inserted into the inside of the socket 15. The present invention is convenient for replacing the worn cutting blade 9. When replacing, there is no need to use tools to assist in disassembly. The operation is simple and convenient, saving time and effort, and improving the efficiency of polyurethane board cutting. When cutting the polyurethane board, by starting the dust removal fan 16, the waste generated during cutting is sucked in through the dust collecting port 21, and then transported to the inside of the collection box 17 through the conveying pipe 20. Then, when the inside of the collection box 17 is full, the waste can be cleaned by pulling the drawer 18 out of the collection box 17. The filter plate 19 is provided to facilitate filtering the collected waste, avoid the dust removal fan 16 from sucking it in, and extend the service life of the dust removal fan 16. It is convenient to collect the waste generated during the cutting of the polyurethane board. The collection of waste can keep the workplace clean and tidy, and reduce the workers' slips or other accidental injuries caused by the scattered waste. At the same time, collecting waste also helps to maintain the cleanliness and safety of the working area.
